JOB SMITH, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO GEORGE O. HETZEL t CO., OF SAME PLACE.

APPARATUS FOR DvElNe.

SPECIFICATION forming part of Letters Patent No. 406,784, dated July 9, 1889.

Application filed April 29, 1889. Serial No. 308,950. (No model.) i

To all whom it may concern: v

Be it known that I, JOB SMITH, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Dyeing-Machines, of which the following is a specification.

My invention relates to that class of machines used for dyeing, washing, or scouring yarn, in which the skeins of yarn are carried through the liquid upon suitable frames; and it consists of certain improvements in the construction and operation of such a machine, as more fully described hereinafter.

It has been proposed to construct a dyeingmachine in which the skeins are mounted upon frames secured to a rotating` reel which carries the yarn into and out of the dyeingliquid; but such machines, even when built of the largest practical. dimensions, have but a limited capacity, and where a large quantity of yarn is to be dyed of the same color or shade it is objectionable to dye such small quantities at a time, for the reason that it is almost impossible to obtain exactly the saine shade in different batches, whereas the construction I propose to employ is capable of dyeing at a single operation any desired quantity of yarn, so that a uniformity of color or shade is secured, which could not be obtained were the yarn treated in small batches at different times.

It has also been proposed to secure the skeins of yarn lengthwise upon endless belts, and to guide such endless belts into and out of the dyeing-liquid by suitable rollers; but, in addition to the limited capacity of themachine so constructed, it is obj ectionable to carry the skeins or hanks of yarn repeatedly over guiding-rolls, as the yarn is subjected to more or less injurious pressure at each such contact.

In the accompanying drawings, Figure l is a longitudinal sectional elevation on the line l 2, Fig. 2, of a dyeing-machine constructed in accordance with my invention. Fig. 2 is a transverse sectional elevation of the same on the line 3 4, Fig. l; and Fig. 3 is a detached perspective view of a portion of the yarn-carrying device.

To suitable bearings in the sides of a vat to the ends of the vat or tank as is permitted by the character of the yarn-carrying frames, the endless chains being close to the opposite sides of the tank. a

To the chainsA are secured at suitable intervals transverse bars a, and to the latter are secured opposite upright bars or posts a', to which are affixed suitable retainers d e, for the reception of transverse bars d e', on which the skeins or hanks of yarn to be dyed are mounted.

It will be noticed that the retainers d have formed in them a series of orices, to any one of which the lower bar d may be adapted, according -to the length of the skein or hank of yarn to be treated. The shaft of one of the sprocket wheels is provided wit-h suitable driving mechanism by which the chains and yarn-holding frames carried thereby may be moved.

The action of the machine is as follows: The skeins or hanks of yarnare first strung upon the bars d e', each of the bars a being provided near each end with a guard or shield f, to prevent the skeins or hanks from working out against the inner sides of the bars a', where the dyeing or scouring liquid cannot gain access to them. The bars cf are then placed in the retainers c, and the bars d' are adapted to such of the orifices of the retailiers d as the lengths of skein or hank render most available. After all of the series of frames have been loaded with yarn in this manner motion is imparted to the endless chains; hence the yarn-carrying frames will be caused to traverse with the chains in the direction of the arrow, and the yarn will be immersed in the liquid at one end of the vat or tank, will be carried through said liquid to the opposite end of the tank, and then lifted from the liquid and returned to the startingpoint, the repeated carryings of the yarn through the liquid causing the access of the latter to all portions of the skeins or hanks during their travel through the tank, so as to effect the thorough scouring or dyeing of the yarn.

IOO

I elaim as my inventionl.V In a machine for dyeing or scouring yarn, the combination of a vat or tank, an endless chain traversing said tank, and a series of yarn-holding frames mounted upon said endless chain, said frames consisting of bars projecting outward from the chain and having lateral yarn-carrying arms, substantially as speeiiied.

2. In a machine for dyeing or scouring yarn the combination of the vat or tank and endless chains traversing said tank with a series of yarn-holding frames mounted upon said endless chains, each frame consisting of a cross-bar 'extending from chain to chain, upright bars extending from said cross-bar, and transverse yarn-carrying rods supported upon said upright bars, substantially as speci- 3. In a machine for dyeing or scouring an endless chain traversing said tank with a series of yarn-supporting frames carried by said chain, each frame having guards to re-. tain the hanks of yarn in proper lateral position, as set forth. or ,i

In testimony whereof l have signed my name to this specification in the presence of two 35 subscribing Witnesses.
